IGF-1, also known as insulin-like growth factor 1, is a complex and interesting hormone because of its ability to produce beneficial and damaging effects on your health, depending on how much your body produces. The most important function of IGF-1 is to promote cell growth (hence the label). IGF is known as a growth factor and is part of a group of hormones that generate cells and tissues that also include epidermal growth factor, thrombocytopenic growth factor, and nerve growth factor.
On the one hand, IGF-1 has some anti-aging effects and improved performance, which includes helping to build and retain muscle mass and bone mass. On the other hand, higher levels of IGF-1 were associated with an increased risk of developing some cancers and even a shorter life expectancy. (1)
We will analyze the good and bad effects of IGF-1, as well as the lifestyle factors that exacerbate IGF-1.
What is IGF-1?
What does IGF-1 mean? IGF-1 means “growth factor like insulin 1”. What is the role of IGF-1? IGF-1 is an activating peptide hormone that has the role of stimulating growth and, to a lesser extent, helps maintain normal blood sugar levels. It used to be called somatomedin (or somatomedin C) because Forskolin Keto Complete it was a peptide in the somatomedin family. (2) IGF1 was identified as a “monopeptide 70 amino acid polypeptide that is crosslinked to 3 disulfide bridges”.
IGF-1 has its current name because it contains some actions similar to insulin in the body (including lowering blood sugar), but not as powerful as insulin when it comes to controlling blood glucose levels. (3) Because many of the effects of human growth hormone are mediated, many people discuss these hormones interchangeably.
The other peptide hormone, which is similar to IGF-1, is called IGF-2. Each of these growth factors has a structure similar to that of insulin. Both are produced mainly in the liver, as well as in other tissues, in response to the secretion of the growth hormone of the pituitary gland. Both are an extension of human growth hormone because they have many of the same effects.
How is IGF-1 and IGF-2 different? The different receptors are activated and activated, causing the growth of different cells and tissues. IGF-1 mainly stimulates hypertrophy (increase in cell volume) and hyperplasia (increase in cell count) in both children and adults. It does so in tissues, including muscles and bones. IGF-2 is very active during fetal development, which aids cell growth (proliferation) and tissue formation, but becomes less active after birth.
